Abstract: PURPOSE:To realize proper control of picture density with a simple constitution, by detecting the toner density through a quantity of electricity induced by the movement of toner to a photosensitive body and controlling the quantity of toner so that the detected level of the toner quantity becomes freely changeable one. CONSTITUTION:When negatively charged electrostatically toner moves to a photosensitive body 1 through a magnetic brush 2b, an induced electric current is made to flow between the photosensitive body 1 and earth in accordance with the quantity of the moving toner and further made to flow to a developing bias power source 6 through the earth and resistance 7. Then the voltage across both ends of the resistance 7 is processed by an operational amplifier 8 and the toner density of the photosensitive body 1 is correctly detected. The detected level is compared with a freely changeable reference detection level at a comparator 9 through a variable resistance 10 and, when the detected toner density is lower than the reference detection level, the output of the comparator 9 becomes a high level. Then a transistor 12 is turned on through an AND gate 10 and a motor 5 which controls a toner feeding roller 4a is driven. By means of these arrangements, proper control of picture density can be realized with a simple constitution.

Abstract: PURPOSE:To decrease the burden of an inspecting engineer and to enhance the reliability of decision by deciding the virus infection of a specimen in accordance with a difference in the fluorescent luminance distribution of the image processing data of the fluorescent image of the antigen positive cells and negative cells subjected to fluorescent dyeing. CONSTITUTION:A sample is first formed by separately arranging the antigen positive cell (+cell) group and negative cell (-cell) group on a preparato and respectively dyeing the cells by an indirect fluorescent antibody method. This sample is then observed with a microscope 1 and the observed images are converted by a TV camera 2 to image data. The data is taken into an image processor 3. The fluorescent images are subjected to analysis processing at this time and the intra- and extra-cellular fluorescent luminance distributions are detected. The data thereof is sent to a deciding device 5 and the characteristic value is calculated by the extra-cellular fluorescent luminance distribution and whether the value exceeds the predetermined threshold or not is judged. The fluorescent luminance distribution in the +cells and the luminance distribution in the -cells are determined. Both are compared and the characteristic value of the specimen is calculated. The infection, non-infection and infeasibility of the decision are determined according to the predetermined standard. The burden of the inspecting engineer is, therefore, decreased and the reliability of the decision is enhanced.
